TURN-TAB LE Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed April 16, 1908. Serial No. 427,299.

To all whom it may concern:

Be it known that I, PAUL KLEMP, a citizen of Germany, residing atDusseldorf, Germany, have invented new and useful Improvements inTurn-Tables, of which the following is a specification.

This invention relates to improvements in turn-tables which are employedtemporarily for establishing turn-tables between two sets of railscrossing each other, which turn-table consists of a turn-disk on thesurface of which rails tongues are arranged and by which rail tonguesother rails can be crossed. By known arrangement the rail tongues mustbe bolted to the main rails, so that the laying down of such aturn-table takes up considerable time and causes much work. Besides thisthe bolting is exposed to heavy lateral pressures, so that it does notalways fulfil the desired requirements. This invention is designed toovercome these disadvantages and I employ in my arrangement a lower orbase-plate, which is provided at its sides with sloping raising planes,which are placed between the rails, the inner circular part of thebase-plate is lowered by bending it in such a manner, that the top ofthe planes are level with the turn disk, arranged in the recess of thebase-plate.

The advantages of my arrangement consist essentially therein, that bythe unity of the base plate not only an important sta bility is obtainedbut also a simple removal without toil and trouble can be efiected andafter having been mounted on the rail crossing it is securely held bythe sloping planes. As before mentioned my turn-plate is of the sameheight as the top of the planes and thus the wagon or the like has notto overcome a gradient by rolling from the sole plate onto theturn-plate. Thus jolting is prevented and the additional motive powerfor drawing the wagon or the like upon the turn-disk is obviated. Thewhole gradient which the wagon has to master from the upper edge of therails is only like the thickness of the plates.

I will now describe my invention with reference to the accompanyingdrawings in which Figure 1 shows a cross section of a turntableconstructed according to my invention and Fig. 2 shows a plan view ofsame, in which the turn-plate is partly broken away.

The base-plate d is shown. placed upon an existing butt-joint railwaycrossing formed of rails 61. and b crossing main-track c whichbase-plate d rests directly upon the top of the rails and engages withits four projecting planes or tongues e sloping downwards, between thesingle sets of rails. Thus the baseplate at is secured in position andprevented from turning or shifting and the base plate also prevents therails shifting. By means of vertically bent stems f each sloping plane arests upon the lower flange of the rai s. In each corner between twosloping lanes 6 guide angles 9 are arranged like col ars proj ectingover the plane of p the base-plate. The wagons are thus shaken less andextraordinary moving power is not needed to cause them to roll upon thesurface of the turn-plate. is bent downwards su' iciently for theturnplate h to be arranged flushly in it. and its face is level with thetop edge of the sloping planes 6. The turn plate h is provided with acircular raised portion i for centering the wagons exactly. The pin orbolt 7c is riveted on the turn-plate 7L and is turnable in a hole in thebase-plate (Z.

My arrangements may be provided with the already known revolving restfor supporting and facilitating the rotation of the turnplate in thefollowing manner. An annular ball race I is pressed into the base plated, in which the balls run and carry plate It. Said balls are kept bymeans of a ball frame at certain distances from each other, which frameconsists of two metal rings and distance pieces 0 regulating thedistances of the balls.

The apparatus may be altered from the construction shown and describedwithout departing from the spirit of the invention.

I claim: 4.
